Berin,
I'm attaching Win32 SSL URI resolver class and test code.
I haven't still finished testing.
I have some doubts. I have noticed that XSECURIResolver
interface doesn't have send() method and resolveURI()
returns BinInputStream.
Without send() I'm not sure how we can use it in SOAP?
Best regards,
Milan
